To argue that we need some technology in order to produce food to tackle hunger is completely blind to the facts on the ground. Actually, what we need is the exact opposite of what GMOs give us. We have to empower farmers to grow food for themselves and plant and grow their own seeds and use practices to deal with weeds and the need for fertility, not from purchased products like a seed or a chemical, but from their own farms, from their own knowledge and skill sets.

People don't realize how much the food industry has infiltrated all aspects of our children's lived experience, including their experience at school. There are sponsored curricula by food companies, they're also in our schools with logos sponsoring sports teams.

The food industry is spending almost $2 billion a year marketing directly to children and teens. We know that those ads lead to children demanding certain brands, and we know that food and drink marketing gets all of us to consume more calories. If we're going to address diet-related illnesses, talking about marketing to kids is a key step. There should be places like schools that are protected sanctuaries from commercialization and from advertising, especially when it comes to kids' health.

You could increase farmworker wages significantly and not change the price to the consumer at all - for instance, if you redistribute how revenue is paid out across the food chain. Labor costs, particularly farm labor, is a tiny portion of the price we pay at the supermarket.

Yes, there is a crisis of hunger on the planet, but hunger is not caused by a scarcity of food but a scarcity of democracy.

Just in the past couple of years, there's been pushback against some of that marketing, as parents have gotten really upset. Now we're seeing Coke and Pepsi kind of shape-shifting. Instead of doing these very explicit marketing deals, they are getting into schools in much more hidden ways - things like My Coke Rewards, where they encourage schools to push their student body to purchase Coke products, in exchange for points that go toward various products for the school. It's a way for these companies to get in front of kids, presented as a form of charity.

When people hear about legal restrictions on marketing and advertising, often the response is: Aren't you just being a food nanny? Isn't that government playing too much of a role in our lives? When people have that response, they're forgetting the extent to which what kids are eating and drinking is having as much of an impact on their lives as, say, if they were starting to smoke cigarettes as teenagers. Diet-related illnesses are causing nearly as many deaths as tobacco-related illnesses.
